Actually, there are loads of graphs. Better still, the comments offer some insight into the foggy science I will now call “nerfology”. There are thoughts from minds such as that of Brian ‘Psychochild’ Green, who observes that no graph can do the complexity of nerfological decision-making true justice:

Yeah, the issue with metrics like this is that you always want more information. Class populations would be interesting, to see how popularity of a class affected balance decisions and vice versa. Also, how do the changes affect different builds, or even different talent trees?

Or indeed, forumite whinging. Speaking of which, I’ll be talking to Eve Online’s development team about nerfing speed later this week.
